Hi guys,
I installed a 6.5" lift on my 03 crew cab short box. Now, in four wheel drive it has a noticable vibration coming from the front end. The front drive shaft is at a pretty good angle- I beleive that is my problem. Does somebody make a front driveshaft with a cv joint? I don't see any options for cv drive shafts from aftermarket companies websites. Any opinions on how to fix this problem is greatly appreciated.

Thats odd that your having vib issues with only 6.5" of lift. Unless something is installed incorrectly or Pro Comp fudged on something you should not have any vibs until 10"+ of lift. Try to isolate where the vibration is coming from if possible. A custom driveshaft from a local shop would be a possible fix, aswell as pinon angle shims, or a transfer case clocking ring. But again, I think something else is going on here....

Thanks for the reply guys. I should mention that when I say vibration, its not that noticable, I get paraniod when it comes to my truck. I asked the wife what she thinks and she said she could hardly notice it, maybe I'm being to picky. NotStock, since you mentioned something might be wrong I called procomp. I talked to Jeff and he said check the slip yoke to see how far its pulled out and check the cv joint at the transfer case. I did a quick visual on that, the yokes look real close- I can't see any space between them but when it sits normal the shaft spins freely. Maybe under torque they are touching? When I had it aligned, he said it was damn near perfect, they didn't have to change the alignment shims. The truck is excellent w/ only 68,000 on her. Very seldom I use 4x4. The truck is in my signiture.

Where are you feeling the vib, the steering wheel? Big tires are hard to balance at times, that could be all it is....

I feel it in the front end, maybe its just normal for it being a 6.5" lift. Its not bad, but I notice everything. When its in 2wd, even with 325's it drives perfect. I don't know, its probably nothing.. maybe its me.

I WOULD SAY CHECK ALL YOUR U JOINTS AND SEE IF THERE IS ANY PLAY IN THEM BECAUSE IF ONE ON YOUR FRONT DRIVE SHAFT CAN MAKE IT VIBRATE AT SLOWER SPEEDS IF THAT IS THE CASE I RAN INTO THAT WITH A COUPLE TRUCKS AT THE SHOP I WORK AT

I'll check tomarrow, maybe the cv joint is getting alittle sloppy. Maybe because I don't use 4x4 that often and is garaged during the winter they are drying up. Thanks

Why would you want a CV joint, also something could have been installed wrong, I have 9.5 inch of lift and never extended my driveshaft its still the stock length and all might wanna relook at everything.

I had a brain fart when I first mentioned a cv joint, I forgot it already had one on the transfer case side. U-joints on the front feel good. But I did notice the front driveshaft does have alittle slop in the slip yoke- maybe a little more then a 1/16".
